Library Skills: OPAC Searching Searching by Subject
OPAC stands for Online Public Access Catalog.
The library’s catalog is online and available from computers: in the library at home anywhere you can “be connected”!
The access points for successful searching are: 1. Author search 2. Title search 3. Subject search
Let’s visit the public library’s OPAC…to experiment with a subject search.
Pull down the Search menuChoose “Subject Browse”For a subject, let’s type in … nebraska
Our subject browse found a “subject heading” for “Nebraska”…with just 9 titles. 9 Titles!
Browse down the list, though, to see more subject headings about “Nebraska”-- Nebraska – Artists Nebraska – Blizzard, 1888 Nebraska – Capitol Nebraska – Cornhuskers (Football team) Nebraska – Floods Nebraska – History – Civil War, – Regimental History
Nebraska – Artists Nebraska – Blizzard, 1888 Nebraska – History – Civil War, – Regimental History Each of these is a “subject heading” —a word or group of words that describes the topic or subject of a library item:
Click on a subject heading to bring up the list of holdings—all of the items in the library that fit with that subject heading. Click the subject heading: Nebraska – Blizzard, 1888… …and a listing of these 4 items will appear.
The first item looks interesting. Let’s click on it and take a closer look… Click here!
A closer look at The Children’s Blizzard shows us that it has 7 subject headings. Each heading is a “hot link” to a listing of more items about that subject.
Look at the Middle West subject heading. ?
Middle West ? That is not a phrase that Nebraskans would normally use to identify our state. Midwest ? Yes! But Midwest is not a “proper” heading used by the Sears List of Subject Headings —the source of the library’s subject headings.
A subject browse for “Midwest” brings up… Nothing !
Midwest would be here!
As you can see, sometimes searching by subject heading can be tricky! Sometimes you have to do a bit of detective work to figure out the subject heading for your topic.
Next time we will learn about a useful way of searching the OPAC using keywords.
Keywords can help you be a good search detective! Keywords are a useful way of searching: Subject headings Authors Titles
Until next time, practice searching the OPAC by subject. What subject headings might describe your favorite hobby? sport? favorite vacation spot? type of music?
Subject headings-- The End.
